u.s. has been briefed about it. if it comes to it, they are now done with the planning and completely ready to go. but ambassador oren does very importantly go on to say, and i quote, we would like to avoid ground action. oren saying they still want to get some sort of solution to all of this, get hamas to agree to stop firing those rockets. if it doesn't happen, though, they are ready to go now, wolf. >> barbara, where do the israelis think the weapons are coming from, the weapons in gaza, the rockets, the missiles? >> reporter: well, this is a very important question, of course, because now hamas is firing in large groups, 15 rockets at a time, up to that many. iran has been a longstanding source of weaponry. but what we have now just been told is the weapons are also coming in from libya. since gadhafi fell, of course, very little government control in libya over those weapons.
